Application filed March 28, 1906. Serial No. 308,598,

T0 all whom t may concern:

Be it known that I, JOHN W. GRAIN, a citi- Zen of the United States,residing at Winchester, in the county of Clark and State of Kentucky,have invented certain new and useful Improvements in Carriage-Machines;and I do hereby declare the following to be a full, clear, and exactdescription of the invention, such as will enable others skilled in theart to which it appertains to make and use the same.

My invention relates to improvements in carnage-machines; and the objectof my invention is to produce a simple and compact be used forspoke-turning, wood-boring, planing, and lathe-Work, and, in fact, forcarriage-making, blacksmithing, and manufacturing generally.

With this object in view my invention consists in the construction andcombinations of parts, as hereinafter described and claimed.

In the accompanying drawings, Figure 1 is a side elevation of myimproved machine. Fig. 2 is a top plan view thereof.' Fig. 3 is asection on theline 1 2 of Fig. 2, and Fig. 4 is a section on the line 34 of the same figure.

a represents the bed of the machine, the main part of which ispreferably formed of parallel I-beams supported on legs y. At the rearthe machine-frame is extended at right angles, as shown at b, anadditional support a being provided at the outer end of said extension.To one end of the bed a is bolted or otherwise secured anupwardly-extending bracket 2, in which is mounted a spindle Z', in whichis adapted to be inserted a lathechuck, (not shown,) which is securedtherein by the screw 3. On the spindle Z are mounted a series of pulleys4 of different sizes, so that the spindle Z may be driven at diherentspeeds.

To one end of the frame a is fastened a table 4, provided with a slot 5,through which the band-saw n is adapted to run. This band-saw passesover pulleys or wheels u and 6, the latter wheel being mounted in anadjustable bearing 7, which is adjustably` supported on thebracket 2 bymeans of the wheel 8. 9 represents guide pins, with which ears l() onsaid bearing engage.

The bracket 2 is provided with a bearing 11 at one end for the receptionof the rod 12, which carries an arm 13, provided with an l ordinaryband-saw guide 14. The band-saw is driven by the rotation of the wheelu, which is loosely mounted on the main or driving shaft 15, to whichpower is supplied by any suitable means. (Not shown.)

The wheel u is held in position on the shaft 15 by collars m and Qc,secured to said shaft. and o represents a clutch slidingly connected bya feather w to the shaft 15, the collar limiting the movement of theclutch 'v in one direction. This clutch may be operated by hand or anysuitable means.

Mounted on bearings carried by the extension b of the frame is a shafta, which carries a circular rip-saw d, which works through a slot 16 ina table c. The shaft a is driven by means of a crossed belt from theshaft 15, said belt running over the pulleys 17 and 1S.

g represents the planer-board, which is located back of the lathe-frame.Through this board the planer f projects upwardly. This planer ismounted upon a shaft 19, which rests in a step h', said step beingslidably supported in a bracket e and adjustable by means of thehandwheel i which carries a screw passing through a projection 20 on thebracket e. The shaft 19 is driven by a belt 21, which passes over apulley 22 on the shaft 15 and also over a pulley 23 on the shaft 19,said belt being crossed and passing. over an idler 24.

25 represents the shaft for driving the lathe, which is mounted inbearings 26 and 27 on two of the supports y. Said shaft is provided witha vbeveled gear-wheel 28, which meshes with a similar gear-Wheel 29 onthe shaft 15. On the shaft 25 are mounted a series of stepped pulleys30, similar in shape to the pulleys 4 on the spindle Z, but oppolsitelyarranged, as is common in lathe-work.

31 represents an idle pulley loosely mounted on the shaft 25, on whichthe lathe-driving belt is adapted to be placed when it is not desired touse the lathe.

b represents the tail-stock or carriage of the machine, Which isslidably mounted on the bed a and which may be moved back and forth asdesired, its forward movement toward the lathe-head, however, beinglimited by the adjustable stop y', which is slidably mounted in a slot32 in one of the I-beams forming the bed of the machine and Which bymeans of a nut may be fastened in any desired position in said slot.This tail-stock IIO position by means of the bolt. 71, and the nutadjusted up and down by means of the handthreaded `perforation in theinside of the Yhand-wheel The block t' is provided with also providedwith a series of clamps e and h,

, As the part .7L ispivotally connected to the vertical spindle m, whichacts as a wheel- Y .block j carries the centering-spindle c forlathe-work, which spindle can be adjusted Yback and forth in the bloclriby means of the led for the purpose of cutting tenons on 4with a nut 1,provides an adjustment for cut- The tail-stock is clamped in any desired35 thereon must of course be loosened before the tail-stock is moved.The tail-stock or carriage I) is provided with a block t, slidablymounted on guides 36 thereon, which can be wheel 7c and screw-threadedrod d. This hand-wheelf, one end of said spindle c being screw-threadedfor engagement with a screwa rearwardly-projecting portion 37, and thehand-wheel f is provided with a projection 38, so that when once placedin position the two parts will firmly engage with each other, while atthe same time permitting the handwheel f to be rotated. The tail-blockl) is the clamps 7L being located ust in front of the block i and theclamps e being adjustable toward and away from the clamps 7L. Thisadjustment is effected by means of the handwheel the spindle c runningbackward and engaging-with a pin Z, held in a cross-frame g, which ispivotally connected to the clamps e..

spindle c, the clamps can be moved in a zigzag direction, so as toadjust themselves to any required angle.

The tail-stock b carries at its outer end a rest on which vehicle-wheelsmay be mountspolres, &c. The thumb-screw o, provided ting tenons vatvarious angles t the center of the spoke.

n represents van adjusting hand-wheel, screw-threaded on the lowerscrew-threaded end of the spindle m. By means of this handwheel, whichrests upon a perforated crosspiece t, the spindle m can be raised orlowered as needed, and a nut r on the lower end of the screw-threadedportion of the spindle m is used to secure the spindle in any desiredposition.

o represents the work-plate, located at the top of the screw-threadedportion of the spindle m, and by the construction described thiswork-plate may be raised or lowered, as desired.

It is obvious from the foregoing description that all of the ordinaryoperation of carriage-building, including sawing, ripping,planing,.drilling, and lathe-work, may all be carried on in this simplemachine. with a great saving` of manual labor and a large economy ofspace, as the machine is only about eight feet long and a littleoverithree feet wide.

I-Iavin` thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is-

l. In a carriage-machine, the combination of a bed, a lathe carriedthereby provided with a tail-stock, a centering-spindle in saidtail-stock, means for adjustingsaid tail-stock, and clamping memberscarried by said tailstock and operated by the movement of said spindle,substantially as described.

2. In acarriage-machine, the combination of a tail-stock, acentering-spindle Vcarried thereby, an operating-wheel for said spindle,clamping members carried by sai'd tailstocl, some of said members beingpivotally connected to saidspindle, substantially asdescribed.

In testimony whereof I a'HiX my signature in presence of two witnesses.
